To all whom it may concern:

Be it known that I, LoUIs W. Ronn- HORST, a citizen of the United States, residing at Columbus, in the county of Platte and State of Nebraska, have invented new and useful Improvements in Radiator-Protectors, of which the following is a specification.

This invention is an improved protector for use on the radiator of an automobile to prevent the cooling water from freezing during cold weather, and it is adapted to be readily opened or closed as desired and it may be readily attached to and removed from a radiator at will, or may be built in, if preferred, when the radiator is constructed.

The invention consists in the construction, combination and arrangement of devices hereinafter described and claimed.

In the accompanying drawings Figure 1 is a front elevation.

Fig. 2 is a horizontal sectional view of my improved radiator protector and showing the same attached to a radiator.

Fig. 3 is a vertical sectional view of the same, attached to the radiator, and on the plane indicated by the line aa of Fig. 1.

Figs. 4 and 5 are detail views.

In the embodiment of my invention I provide a frame 1 which is adapted to fit against the front side of a radiator, such as indicated at A in Figs. 2 and 3. This frame comprises a pair of vertical bars 2, a lower cross bar 3 and a cross bar 4 which is secured to the said vertical bars at a suitable distance from their upper ends. The bars of the frame may be made of any suitable material, such for instance as strips of sheet metal, steel, iron,- aluminum or the preferably made of sheet metal is secured to the vertical bars, on their front sides, and at a suitable distance from their lower ends. The vertical bars throughout their intermediate portions, between the fixed shutter slat and a point near the upper cross bar 4 are 1 angled cross sectionally and provided with forwardly extending flanges or Webs 6 at their opposing sides. The vertical bars are here shown as having their upper ends provided with rearwardly extending laterally inclined arms or bags 7 t0 bear on the top of the radiator. ushioning strips 8, of

asbestos .or other suitable material are secured on the rear sides of the vertical bars, to bear directly against the front side of the radiator.

I also provide a series of pivotally mounted shutter slats'9 which are made of suitable material, such for instance as suitable sheet metal, each of the said slats 9 being provided, on its inner side and edge with lugs 10 integral therewith and bent therefrom and the recesses 11 from which the said lugs are bent serving to clear the flanges or webs of the vertical bars. The lugs 10 are arranged on the opposing sides of the flanges of the vertical bars and are pivotally connected thereto as at 12, thereby. effecting hinge joints or connections between the shutter slats 9 and the vertical bars of the frame and adapting said shutter slats to be arranged in either opened or closed position.

Each pivotally mounted shutter slat is also formed, at its front edge, and at a suitable distance from one side, with an upstanding lug 13 which is bent therefrom and which being displaced forms a recess 14. These recesses serve to clear and receivea connecting rod 15 to which the said lugs of the pivoted shutter slats are pivotally attached as at 17. A spring 18 is provided which is here shown connected to one of the vertical bars and also connected to the upper end of said connecting rod, said spring acting to normally hold the shutters in open position.

A rock shaft 19 is mounted in bearings 20 at the ends of the lower crossbar 3, and

has a rock arm 21 at its inner end which is pivotally connected by a link 22 to the con necting rod of the pivoted shutter slats, the said rock shaft being provided at the outer end or opposite end with a crank arm 23 which is connected by an operating rod 24 to a lever 25. This lever, which serves to control the protector, is pivoted as at 26 in a base 27, the said base having a rack 28 and thesaid controlling lever being provided with a pawl 29, which is pivoted as at 30 and is caused by a spring '31 to normally engage the rack, the pawl thus serving to hold the controlling lever and hence also the movable slats of the protector, in any desired position, either entirely opened or closed, or in partly closed position.

driver may place his foot to operate said The 'controlljng'l'ever has a head 32 on which the 33 which enables it to be readily disengaged from the rack. To secure the protector in place on the front side of the radiator I provide holes 34, of which any suitable number may be used, which are placed on the rear' side of the radiator and each of which has on its rear or outer side an arched portion 35 and'is provided with openings 36, 37. Screw eyes 38 have their threaded stems extended through the opening 37 and are provided with securing and adjusting nuts 39 which bear on the rear sides of the arched portions 35. Wires 40, which in practice are preferably flexible copper wires are passed through openings in the vertical bars of the protector frame, rearwardly between the tubes of and through the radiator and are attached to the eyes of the screws 38. By tightening the nuts 39 the screws cause the wires to be put under the required tension to hold the protector securely against the front side of the radiator.

aeaeee Having thus described my invention ll claim A register comprising a frame including connected vertical and transverse members,

means for securing said frame to a support, said verticalmembers each being formed to provide a forwardly extending flange, a p111- rality of shutter slats having stamped out lugs pivotally mounted on saidflanges, the

openings resulting from the stamping out LOUIS W. RODEHORST.
